Isingeniso esifushane seIshubhu lesithombe le-Ultraviolet:

I-Ultraviolet phototube uhlobo lweshubhu lokuthola i-ultraviolet elinomphumela we-photoelectric. Lolu hlobo lwe-photocell lusebenzisa i-cathode ukukhiqiza i-photoemission, ama-photoelectron aya ku-anode ngaphansi kwesenzo sensimu kagesi, futhi i-ionization yenzeka ngenxa yokushayisana nama-athomu egesi eshubhu ngesikhathi se-ionization; ama-electron amasha nama-photoelectron akhiwe yinqubo ye-ionization womabili amukelwa yi-anode, kuyilapho ama-ion amahle amukelwa yi-cathode ngakolunye uhlangothi. Ngakho-ke, i-photocurrent kusekethe ye-anode inkulu ngokuphindwe kaningana kunaleyo eshubhu le-vacuum photo. Ama-photocell e-Ultraviolet anemiphumela ye-photovoltaic yensimbi kanye ne-gas multiplier angabona imisebe ye-ultraviolet ebangeni eliyi-185-300mm futhi akhiqize i-photocurrent.

Ayizweli emisebeni engaphandle kwalesi sifunda se-spectral, njengokukhanya kwelanga okubonakalayo kanye nemithombo yokukhanya yangaphakathi. Ngakho-ke akudingekile ukusebenzisa isivikelo sokukhanya esibonakalayo njengamanye amadivayisi e-semiconductor, ngakho-ke kulula kakhulu ukuyisebenzisa.
I-Ultraviolet phototube ingathola imisebe ye-ultraviolet ebuthakathaka. Ingasetshenziswa ku-oyela kaphethiloli webhoyila, ukuqapha igesi, i-alamu yomlilo, uhlelo lwamandla lokuqapha ukukhanyisa kwe-transformer engagadiwe, njll.
